2 Claims.

This invention relates to window structures of the type in which windowsashes are slidable in window frames and are frictionally held inadjusted position without the use of pulleys, sash cords or,counterbalancing weights.

It is a` primary object of the invention to provide improved andsimplied guide channels and slider element structuresA for the sasheswhich can be readily applied in standard window frames without changestherein, so that our invention may be readily applied to existing aswell as newly installed windows.

A further object of the invention is to provide improved structure andarrangement for more readily detaching the window sashes from theirguide structures so that the sashes may be bodily removed from theframes for purposes of decoration or repair, or for washing. I

Another important object is to provide simple guide and slider elementsfor supporting and aligning the sashes and which will cooperate tofunction efliciently to seal the window against the weather without needof special weather stripping or other special sealing means.

The various features of our invention are incorporated in the structureshown on the drawings, in which drawings:

Figure l is a front elevation of a Window comprising upper and lowersashes;

Figure' 2 is an enlarged cross section on plan II-II of Figure 1;

Figure 3 is an enlarged section on plane III-III of Figure 1;

Figure 4 is an enlarged section on plane IV-IV of Figure 1;

Figure 5 is a section like Figure 4 showing the lower sash raised andthe upper sash shifted down in the frame;

Figure 6 is a section like Figure 5 showing the lower sash detached fromits guide elements and ready to be bodily removed from the frame;

Figure 7 is a section on plane VII--VII of Figure 4;

Figure 8 is a section on plane VIII--VIII of Figure 5;

Figure 9 is a section on plane IX-IX of Figure 2; and

Figure 10 is a section on plane X-X of Figure 9.

Referring to Figures 1, 2 and 3, the window frame shown is of the usualstandard construction comprising the sill ID, the upper rail II, and thesides or uprights I2. Along the inner edges of the sides I2 aredetachably secured the molding stops I3 and along the outer edges of thesides are the usual blind stops I4, a top stop strip I5 secured to theupper rail II registering with the stops I3. v

At each side of the window frame are a pair of inner and outer guidechannel bars I6 and I'I which extend between the sill and top of theframe and are confined transversely between the inner and outer stops I3and I4. 'Ihe inner channels I6 form guideways for the inner sash I andthe outer channels I form guideways for outersash O. As best shown onFigure 10, each guide channel bar is of rectangular U-shaped crosssection comprising the back wall I8, the side walls I9 and 2U and theretaining flanges 2| and 22 extending inwardly from the side walls intoparallelism with the back wall. l

Referring particularly to Figures 7, 9 and 10, in each of the channelsI6 is a slider element S of a length equal substantially to the heightVof the inner sash I. Each guide element comprises a comparatively widestrip 23 and a narrower strip 24 with one or more springs 25 between thestrips tending to urge them respectively into friction engagement withthe side walls I9 and 20 of the guide channel, the strips being of adepth for friction engagement with the back Wall of the channel and theretaining flanges 2l and 22 respectively. As shown on Figure 9 thesprings 25 may be leaf springs with their deflected ends 25 anchored inslits 26 provided in either of the strips 23 or 24. Dowel pins 21extending from the strip 23 extend into passages 28 in the strip 24 tohold the strips in alignment.

As best shown on Figures 2, 5 and 7, the strip 23 of each slider elementS has embedded therein near its upper end a nut member 29 for receivinga screw 30 extending through a passage- Way 3I at the upper end of thecorresponding side of the inner sash I so that when the screws areapplied, the inner sash willV be secured to the slide elements in theopposite channels I6. When the inner sash is raised or lowered theslider'elements S to which it is secured will move in the guide channelsIB and the frictional engagement of the spring-pressed slider strips 23and 24 with the Walls of the guide channels will hold the sash in anyadjusted position.

In order to hold the Asash in longitudinal alignment with the sliderelements S, the slider elements are provided with guide rails or tongues32. This tongue may .be 'a separate piece secured to the slider elementstrip 23, or may be integral therewith as shown on Figure 10. Forreceiving these guide'rails or tongues 32, the

-sash sides have the longitudinal extending channels 33 cut therein as`best shown on Figure 2. The tongues 32 terminate a distance above thelower ends of the slider element strips 23, and in the lower ends of thechannels 33 stop pieces 34 are secured for abutting at their upper endswith the lower ends of the guide rails 32 when the sash is secured tothe slider elements by the screws 30, this abutting engagement assistingthe screws in holding the sash and slider elements against relativelongitudinal displacement. In order to assist the screws in holding thesash and the slider strips together laterally, the labutting ends of theguide rails and the stop pieces 34 may be undercut or beveled asindicated at 35.

Describing now the procedure for bodily removing the inner sash from thewindow frame, it will be noted on Figure 2 that the Width of the sash issligthly less than the distance between the front stop strips I3. OnFigure 4 and in full lines on Figure 7 the inner sash I is shown in itslower or closed position with the screws 38 applied to secure the sashto the slider elements S. To release the sash for bodily removal fromthe frame, the screws 30 are withdrawn and the sash is raised as shownon Figures 5, 8 and by the dotted lines on Figure 7. Due to the abuttingengagement of the stop pieces 34 on the sash with the ends of the guidetongues or rails 32 on the slider elements, the slidel` elements will beshifted up in their guide channels I6 with the sash. The sash is nowshifted down to its .normal position along the guide tongues or rails32, the slider elements being retained at the upper ends of the channelsI6 by their frictional engagement with the channels. The sash channels33 being now free of the tongues 32, the sash may be bodily removed fromthe window frame. To reapply the sash, it is set on the sill I inalignment with the'channels I6 and then shifted upwardly for receptionof the tongues 32 in the sash channels 33 and the screws 30 arereapplied and the sash together with the slider elements is shifted downto its normal closed position. It is evident that, in order to removethe sash, it could first be raised to its upper position and the screws30 then removed, and the sash then shifted down forbodily removal fromthe frame.

The outer sash O is mounted in the guide `channels II by slider elementsS in the same manner as the inner sash. To bodily remove the outer sash,the usual procedure would be to rst raise the inner sash and then lowerthe outer sash and remove the screws 30 from the outer sash. The outersash, after raising thereof together with the slider elements would thenbe shifted down along the slider element guide tongues 32 to withdrawthe sash from the tongues so that the sash could then be bodily removedfrom the frame. To reapply the outer sash it is set on the sill inalignment with guide channels I'I and then shifted upwardly forreception of the tongues 32 by the sash channels 33, and then after aslight downward shift of the inner sash the screws 30 could be reappliedto the upper sash.

Another way of reapplying the sashes would be as follows. For reapplyingthe inner sash, the sash could be set on the window frame sill and theslider elements S shifted downwardly with their tongues 32 in the sashchannels 33, and the screws 30 then applied. 'For reapplying the outersash, it could be set on the sill and then, after suilicient downwardshift of the inner sash for access to the slider elements for the outersash, these slider elements could be shifted down for re-engagement withthe outer sash channels 33 and application of the screws 3U. Thus forbodily removal of a sash from the frame, all that is necessary is towithdraw the screws 38 and vertically shift the sash for disengagementfrom its slider elements, and for reapplication of the sash all that isnecessary is to set it into alignment with the guide channels and shiftit vertically into reassociation with its slider elements, and thenreapplication of the securing elements, such as the screws shown.

When the stop strips I3 are applied to the window frame, the channels I6and I'I will be held with their inner side walls in intimate engagementand their outer side walls in intimate engagement respectively with thestop strips I3 and the strips I4, so that weather-tight joints result.The springs 25 will hold the strips 23 and 24 of the slider elementsagainst the side walls of the guide channels, and the beveled abutmentengagement 35 between the strips 23 and the sash stop pieces 34, and thescrews 3|, will hold the tongues or rails 32 intimately in the sashchannels 33, and the retainer flanges 2| of the guide channels will beintimately en gaged by the slider element strips 23 and the side wallsof the sash adjacent to the channels 33, so that tight weather jointsare provided. The retainer flanges 22 of the guide channels will beintimately engaged by the sash sides adjacent to the channels 33. Withour improved arrangement it is therefore unnecessary to provide specialweather stripping or weather sealing elements.

The slider strips are free at all times to be pressed by the springs 25against the guide channel side Walls 20 to maintain the necessaryfriction between the slider elements and the guide channels for holdingthe sashes in raised positions.

As shown on the drawings, Window sashes and the slider elements S areshown as constructed of wood. It is evident, however, that thesestructures may be of metal. Where the sash is of wood, metal plates 36are preferably provided to form seats for the screw heads and to preventcutting or marring of the wood.

We have shown practical and efficient embodiment of the various featuresof our invention, but we do not desire to be limited to the exactconstruction, arrangement and operation shown and described as changesand modifications may be made which will still come within the scope ofthe invention and the appended claims.

We claim as follows:

1. In a window frame having outer and inner stops at each side, a pairof sheet metal guide channels at each side of the frame extending fromthe top to the bottom thereof and held laterally by the frame inner andouter stops, said channels along their outer edges having each inwardlydirected retaining anges, a slider element in each channel confinedtherein by the retaining iianges of the channel and having slidingmovement in the channel longitudinally thereof, friction means for eachslider element tending to hold it in any position in the respectivechannel, an inner window sash between opposed channels and having tongueand groove connection with the slider elements in said channels, anouter sash between the opposed other channels and having tongue andgroove connection with the slider elements in said channels and havingdetachable means for securing it to said slider elements, the frictionalengagement of said slider elements in the channels being sufcient tohold the respective sash in any position thereof in the frame whereby,after movementl of a sash with the slider elements therefor to on-e endof said frame and subsequent release of the securing means, the sliderelements will remain at such end of the frame and the sash may be movedtoward the other end of the frame away from the slider elements forbodily removal of the sash from the frame.

2. In a window frame having a channel at each side thereof, a sliderelement in each channel for sliding longitudinally therein, a windowsash having tongue and groove connections at its sides with said sliderelements, securing means for securing said sash to said slider elementsfor movement of said elements with said sash when said sash is raised orlowered, means eiecting suicient friction between said slider elementsand said channels for holding said sash in any adjusted position in saidframe, cooperating bevelled abutments on said sash and said sliderelements functioning independently of said securing means to hold saidsash and slider elements laterally together and to cause said sliderelements to move with said sash when said sash is raised but permittingdownward movement of said sash relative to said slider elements, saidsecuring means being releasable so that, after movement of said sashWith said slider elements to the upper end of said frame, said sliderelements will be frictionally held at such end and said sash may bemoved in downward direction for longitudinal disengagement thereof fromsaid slider elements and bodily removal from the frame.
